Area enclosed by the PV (pressure-volume) and TS (temperature-entropy) diagrams shows the work done by the system.
W = F D W = ( F / A ) ( A D ) W = P ( AD ) W = P (V) Work = area under the curve on a P-V diagram.
The following is just an informal discussion, to show why it is reasonable. Work = force x distance. Now, it requires a force to compress a gas. For simplicity, assume a piston of constant diameter. At higher pressures, the force required is greater. And a greater change in volume implies a larger distance.
Phase diagrams usually show phase transition boundaries relative to two variables. WHICH two variables depends on what they're trying to show, but usually is is two of the following: Temperature Pressure Volume/density Mole fraction Mass fraction ========== PT PV less commonly - TV Isobaric T vs mole fraction (e.g. melting point diagram) Isothermal P vs mole fraction (e.g. a vapor pressure diagram)
At engineering level technically both process are same except there definition both process give hyperbolic curve in P-V diagram and straight line in T-S diagram. and even in polytropic process PV^n=constant if n=1 then it is not hyperbolic process it is isothermal process even though the definition says pv=c is hyperbolic process.
PV Crystalox Solar was created in 1982.
yes, the pv diagram is a three dimensional view.
